Application filed November 14, 1907. Serial No. 402,168.

To all whom it may concern:

Be it known that I, SAMUEL J. WEBB, a citizen of the United States,residing at Minden, in the parish of Webster and State of Louisiana,have invented certain new and useful Improvements in Motors, of whichthe following is a specification;

My invention relates to motors and especially to that class of motors inwhich the power is derived from the use of gases or a gaseous mixtureunder pressure, and my invention consists in means whereby to rapidlyand continuously produce such an admixture by the combustion of amixture of air compressed by the action of the motor, and a vaporized orgaseous fuel, as set forth hereinafter, and illustrated in theaccompanying drawing, in which- Figure 1 is an elevation in part sectionshowing my apparatus in connection with a motor and a compressor whichmay be of the rotary type and of any suitable construction; Fig. 2 is anend View; and Fig. 3 an enlarged sectional view of the mixer.

The compressor A and motor B m'ay be of any suitable character, but asindicated each is rotary, and the shaft of the motor is extended tooperate the compressor which has inlets at as through which the airenters and a discharge pipe 9 provided with a suitable check valve 10and leading to an air tank or receptacle E. With the motor is connecteda supply pipe 12 through which the motor fluid passes.

In the construction illustrated in the drawing, the fluid supplied tothe motor consists of the expanded gases resulting from the combustionof an admixture of air and liquid fuel or gas, and the expanded gases ormotorfiuid thus produced are secured by introducing a mixture' of airand fuel through a pipe 3 into the combustion chamber y of a casing C,which communicates with the pipe 12, the air being carried underpressure from the compressor A or the reservoir E in which it is storedthrough a pipe 2 provided with a check valve 14 and with a suitablecontrol valve 9.

The proper admixture of air and liquid fuel is effected in a mixer D.This mixer has a casing 16 communicating with the pipes 2 and 3 betweenwhich is a port 17 closed by a valve 5 and a channel 18 communicatingwith the pipe 7 is closed by a valve 6, the channel 18 and the port 17being of different sizes and the valves 5 and 6 being so proportioned,and both being car-- a means of a handle 19, but to vary the proportionsin consequence of difference in the character of oils used the valve 6is carried by a screw stem 20 adjustable in the stem 4. The pipe 7communicates with an oil reservoir H that'is provided with a check valve21 and control valve 8, and the reservoir H communicates with thereservoir E through a pipe 23 provided with a control valve 24. By thismeans there is a constant pressure upon the oil tending to carry itforcibly to the mixer, and there is a constant pressure upon the'airtending to force it through the mixer, and when the control valves areproperly adjusted the air and the oil will be carried to and through thepipe 3, and the oil will be dispersed or sprayed or atomized formin withthe air a combustible mixture whlc'h passes to the combusion chamber y.

In the combustion chamber the mixture may be ignited in any suitablemanner, as by means of an electrical igniter 26, and so long as themixture is supplied and the heated gases withdrawn there will be acontinuous combustion and the formation of a motor fluid under pressure,which passes to the pipe 12 and operates the motor B.v

In order to maintain the combustion within the receptacle C I provide arefractory body or material 29 which will become highly heated by theburning mixture, and in case of temporary cessation of the flow to orfrom the chamber will serve .to ignite the fresh mixture as soon asintroduced. i

The air which is compressed in and forced from the compressor A will bestored to a certain extent in the receptacle E and prevented fromflowing back by the check valve 10 so that the motor may be startedbymeans of the air thus held under pres-. sure in the receptacle E. Inorder that the motor may be started before any mixture is introduced andignited, I make use of the tank or receptacle F which communicates withthe pipe 12 through a pipe provided with a check valve closing againstthe pressure in the tank F, but capable of being .ceptacle 0 ma the tankE, and so as to insure a flow of air from the mixer into the chamber andcontrol the same automatically.

It will be seen that by the arrangement I above described I am enabledto afford a constant supply of motor gases under pressure to the motorand to maintain the compressor in operation, and that the compressed airthus obtained is effectually employed to furnish the necessary amount ofair to the mixture of air and liquid fuel, and also to vaporize oratomize the latter, but it will of course be understood that in somecases I may use gas instead of liquid fuel, or may vaporize the liquidfuel before combining it with the air. The motor thus put in operationby the continuous generation of gases as above described is suitablygeared as by means of a pinion 30 with any part which has to be driventhereby.

It will of course be understood that the motor gases from the apparatusC may be used for operating a plurality of motors together orindependently,'for which purpose one or more branch pipes 31 providedwith control valves 32 may be used. The flow to the engine may becontrolled by a throttle 40, While the air may flow freely to thecompressor at all times, I prefer to cut it off automatically wheneverthe pressure tends to exceed that which is required. For this purpose Icontrol the air inlet pipe 33 leading to the inlet at av by means of agovernor valve 34 controlled by an ordinary pressure regulator 35, whichis supplied with 1. An apparatus of the class described comprising asource of compressed air,

means for maintainin the pressure of the air below a predeterminedamount, a working fluid generating chamber, a fuel supply ch amber, amixer, means connecting the source of compressed air with said mixer,means connecting the fuel chamber with said mixer, means connecting thesource of compressed air with said fuel chamber, means connecting saidmixer with said generating ch amber, and a safet valve on saidgenerating chamber and a apted to maintain the pressure in saidgenerating chamber below the pressure in said source of compressed air.

2. An apparatus of the class described comprising a source of compressedair, means for maintaining the pressure of the air below a predeterminedamount, a working fluid generating chamber, a fuel supply chamber, amixer connected with said gener ating chamber, means connecting thesource of compressed air with said mixer, means connecting the fuelchamber with said mixer, said mixer havingmeans for simultaneouslyvarying the supply of air and fuel in fixed proportions, meansconnecting the source of compressed air with said fuel chamber, and.

asafet-y valve on said generating chamber adapted to maintain thepressure in said generating chamber below the pressure in said source ofcompressed air.

In testimony whereof I afiix my signature in presence of two witnesses.
